Would you be brave enough to confront the woman in the long skirt? The Washington Post reports:

Police in the Brazilian city of Sao Paulo are baffled by a macabre puzzle: someone has been leaving gift-wrapped human skulls around town.

The first skull in cherry-red wrapping was found on February 20 in a planter near a residential building downtown. Since then, seven others have been found near Mormon temples or consulates, including those for Russia, the Czech Republic and South Africa. The skulls are old, with traces of dirt.

Investigator Paul Henry Bozon Verduraz Verduraz says security cameras captured images of a woman in an ankle-length skirt leaving the skulls, which seem old, with traces of dirt. He thinks this may be part of some sort of ritual.
